Passive Alarm System for Blind and Visually Impaired Individuals

Reference#: P01268

The device assists those who are visually impaired and, in particular, warns blind or visually impaired travelers that they have entered a potentially dangerous area proximal to the edge of boarding platforms of the type typically found in public railway transit systems. An Infrared Integrated Information System consists of an array of infrared transmitters and a portable detector/warning device to be held by the blind traveler. The transmitters create a beam of infrared light that bathes the section of the platform proximal to the platform edge. As the traveler moves into the region of the platform covered by the emission, the sensors in the warning device are activated and by radio, tactile, or other stimuli alert the traveler of the entry into the danger zone.
